Multi-raw-material mixing equipment for 3D printing equipment

The invention relates to the technical field of mixing devices, in particular to multi-raw-material mixing equipment for 3D printing equipment, which comprises a storage box, a plurality of rotating shafts are arranged on the inner wall of the storage box, the plurality of rotating shafts are annularly distributed, arc-shaped plates are mounted at the ends of the rotating shafts, connecting ball grooves are formed in the outer ends of the arc-shaped plates, and connecting balls are rotatably embedded in the connecting ball grooves. A square sliding rod is horizontally installed on the outer wall of the connecting ball, a rotating ring is arranged in the storage box, and the outer end of the square sliding rod penetrates through the rotating ring and is in sliding connection with the rotating ring. The raw materials are stirred by adopting the rotating ring which reciprocates on the vertical plane and the horizontal plane, so that the stirring comprehensiveness of the raw materials can be effectively improved,
